CVE-2026-107813 is a high-severity flaw (CVSS 8.8) affecting nginx ui. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, the api/cluster router exposes node and namespace mutation operations and cluster-wide Nginx reload or restart operations with AuthRequired but without RequireSecureSession. An authenticated OTP-enabled user possessing a stolen or persisted JWT can therefore perform node CRUD, read or replace node credentials, change namespaces, and invoke nodes/reload_nginx or nod

nginxui nginx ui UPGRADE

Affected: >= 2.0.0 and < 2.5.0

Fixed in: 2.5.0

Safe to downgrade to: a release before 2.0.0

1. Check installed version

apt-cache policy nginx-ui || rpm -q nginx-ui || nginx-ui --version

2. UPGRADE to 2.5.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade nginx-ui

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade nginx-ui

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.0.0 (Debian / Ubuntu)

apt-cache madison nginx-ui sudo apt install nginx-ui=<VERSION_BEFORE_2.0.0> sudo apt-mark hold nginx-ui

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list nginx-ui sudo dnf downgrade nginx-ui-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add nginx-ui

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
